Filed: 1987-09-04
Abstract: PURPOSE:To enable execution of comfortable heating operation and to improve a heating effect, by a method wherein, when a difference between high and low temperatures in a room to be air-conditioned exceeds a given value during heating operation, capacity of a capacity control compressor is repeatedly changed in a given range at intervals of a given time. CONSTITUTION:During heating operation, high temperature high pressure gas discharged from an inverter compressor 1 is fed from a 4-way valve 2 to an indoor unit 8 through a connection piping 12b and is radiated and condensed by means of a heat exchanger 9 on the indoor side to perform heating. The gas is fed to an outdoor unit 7 through a check valve 11 and a connection piping 12a, and the heat thereof is absorbed the gas is vaporized by means of a heat exchanger 3 on the outdoor side the pressure of which is reduced by means of a pressure reducing device 4 for heating. The gas is circulated to the inverter compressor 1 through the 4-way valve 2 and an accumulator 6. In this case, when a difference between high and low temperatures in a room 13 to be air-conditioned detected by a temperature difference detecting device 14 exceeds a given value, repeat operation is performed in which frequency to the inverter compressor is increased for a given time by means of a control device 15 to increase discharge air temperature and after that frequency is decreased for a given time to decrease discharge air temperature.

Title: Polarized light source
Inventor: SHINOZAKI JUNICHIRO
IPC: G02F1/13
Filed: 1988-09-06
Abstract: PURPOSE:To polarize the projection luminous flux from a lamp effectively and make the luminous flux bright by separating transmitted light and reflected light by a beam splitter, and then rotating the axis of polarization of one light beam by 90 deg. and projecting both pieces of luminous flux which are in the same polarizing direction almost in parallel by the reflection of a mirror surface. CONSTITUTION:The light projected by the lamp 1 is made into nearly parallel luminous flux by a reflector 2. Then this luminous flux is separated by the beam splitter 3 into S polarized light as reflected light and P polarized light as transmitted light; and the reflected light S is changed in direction by a reflecting mirror 5 and passed through a half-wavelength plate 6 to rotate the axis of polarization by 90 deg., so that the light is in the same direction with the transmitted light. Then, both pieces of luminous flux are made nearly parallel and projected in parallel as polarized light beams in the same direction. At this time, even when the half-wavelength plate is arranged in front of the reflecting mirror 5, the same effect is obtained. Consequently, the polarized light source is obtained which has is small in the loss of the projection luminous flux of the lamp and much brighter than before and has a high utilization rate.

Title: Focus servo circuit for optical disk
Inventor: TATSUGUCHI KAZUO
IPC: G11B7/09
Filed: 1987-09-04
Abstract: PURPOSE:To stably detect a signal, by sending out the signal of pulse width being longer than the time constant of an automatic gain control circuit by a monostable multivibrator and operating normally the driving circuit of an objective lens, when an output of a laser beam is switched to the decreasing direction. CONSTITUTION:When the recording mode is changed to the reproducing mode, the light quantity signal of a waveform (h) of a figure (k) of a matrix circuit 8 is almost the same as a recording/reproducing mode switching signal, and this light quantity signal becomes a waveform (l) differentiated by a time constant of a figure L. Also, the output waveform of a Schmitt circuit 13 becomes a waveform (m) of a figure M, and becomes negative by the delay portion of a leading edge of a response speed of an AGC 11. On the other hand, when the switching signal of a waveform (k) is supplied to an input terminal 15, a monostable multivibrator 16 generates a positive pulse signal being larger than a time constant of the AGC 11, such as the waveform (n) of a figure N. Accordingly, the recording mode is switched to the reproducing mode, and even if the output of a laser beam decreases instantaneously, the output signal of an OR circuit 17 always becomes positive as shown by the waveform (o) of a figure O. Also, since the output signal of a zero crossing detecting circuit 9 also becomes positive, the output of an AND circuit 14 becomes positive, and a driving circuit 5 operates a driving mechanism 6.

IPC: H04N1/00
Filed: 1990-08-23
Abstract: PURPOSE:To secure communication with high responsiveness by outputting an alarm showing the generation of communication error when there is no retransmission from the same communicating party as that of communication generating error within prescribed time after the error is generated. CONSTITUTION:When communication is received within the prescribed time after the communication error is generated at a reception side terminal, it is confirmed by comparing transmission terminal identification signals(TSI) between the communication and the communication generating the communication error whether the retransmission is executed from the same communicating party when generating the communication error or not. When there is no retransmission from the same communicating party within the prescribed time, the picture of the alarm showing the generation of communication error is outputted. Therefore, even when an operator is away from the facsimile equipment during communication, the generation of communication error can be confirmed. Thus, communication with high responsiveness can be secured.

Title: Gas insulating switch
Inventor: KOIZUMI MAKOTO
IPC: H02B13/02
Filed: 1987-09-09
Abstract: PURPOSE:To improve the reliability by injecting a liquid metal on the contact face between a movable piece and a fixed piece and the contact face with a bus connecting metal and grasping the decrease of the contact pressure due to the abrasion of the contact faces and the loosening of fastening bolts in advance. CONSTITUTION:When a liquid metal is injected into gaps between a movable piece 1 and a fixed piece 1 or on the contact face with a bus connecting metal, it is brought into contact with both races forming the gaps and expanded in the gaps. When the width of the gap is changed, the contact is invariably kept following it. Even if the width of the gap is expanded due to the abrasion of contact faces and the loosening of fastening bolts, the contact electric resistance is hardly changed. The temperature rarely rises due to the increase of the contact electric resistance. When the width of the gap is increased, the fluid resistance of the liquid metal is decreased, the pressure loss resulting from the fluid is decreased. The width of the gap can be thereby estimated by monitoring the injection pressure of the fluid metal, and the abnormality of the contact faces can be found.
